摘要：
The unique dynamics of a water droplet over a hot copper substrate due to Leidenfrost evaporation has been reported here. The phenomenon is captured by a high speed camera and analyzed by image processing. During its entire lifetime, the droplet is observed to undergo several shape changes accompanied by simultaneous oscillation and rotation. Further the effect of depletion of droplet volume and substrate temperature on Leidenfrost phenomenon has also been reported. (C) 2014 Elsevier Inc. All rights reserved.
